背景：腰肌已被证明可以通过计算机断层扫描（CT）对肌肉面积的量化来预测患者的预后。其他肌肉形态分析的准确性还没有明确的描述。在这项研究中，我们确定了颞肌质量、腰肌面积、年龄、体重指数（BMI）和性别之间的相关性。方法：对2004年至2011年间在密歇根大学进行腹部和颌面CT扫描的所有创伤患者的颞肌和腰肌尺寸进行测定。年龄、BMI和性别通过图表复习获得。进行单因素和多因素分析，以确定颞肌和腰肌的形态数据之间的相对关系，以及这些信息与临床变量（如BMI、年龄和性别）相对应的能力。结果：本研究共纳入646例患者。249名女性（38.5%）和397名男性（61.5%），平均年龄49.2岁，平均BMI为27.9 kg/m(2)。腰大肌总面积与平均颞肌厚度直接相关（r = 0.57, P < 0.001）。年龄与腰肌面积（r = -0.52, P < 0.001）、颞肌厚度（r = -0.36, P < 0.001）有间接相关。腰大肌和颞肌的测量值与BMI都没有很强的相关性（r = 0.18, P < 0.001; r = 0.14, P = 0.002），尽管在一个更“虚弱”的亚组中发现了更强的相关性，这是由BMI定义的
Background: The psoas muscle has been shown to predict patient outcomes based on the quantification of muscle area using computed tomography (CT) scans. The accuracy of morphomic analysis on other muscles has not been clearly delineated. In this study, we determine the correlation between temporalis muscle mass, psoas muscle area, age, body mass index (BMI), and gender.Methods: Temporalis and psoas muscle dimensions were determined on all trauma patients who had both abdominal and maxillofacial CT scans at the University of Michigan between 2004 and 2011. Age, BMI, and gender were obtained through chart review. Univariate and multivariate analyses were performed to determine the relative relationship between morphomic data of the temporalis and psoas muscles and the ability of such information to correspond with clinical variables, such as BMI, age, and gender.Results: A total of 646 patients were included in the present study. Among the 249 (38.5%) women and 397 (61.5%) men, the average age was 49.2 y. Average BMI was 27.9 kg/m(2). Total psoas muscle area directly correlated with mean temporalis muscle thickness (r = 0.57, P < 0.001). There was an indirect correlation between age and psoas muscle area (r = -0.52, P < 0.001) and temporalis muscle thickness (r = -0.36, P < 0.001). Neither psoas nor temporalis measurements correlated strongly with BMI (r = 0.18, P < 0.001; r = 0.14, P = 0.002), although stronger correlations were found in a more "frail," subgroup as defined by a BMI of
